Similar to Comondu, Mulege more than makes up for its lack of luxuries with practically untouched nature and historical sites, including 10,000-year-old cave paintings. Experience bighorn sheep in their natural habitat, taste some of the world's freshest seafood and venture into the El Vizcaino Biosphere Reserve, a UNESCO World Heritage Site and the largest wildlife refuge in Mexico.
